Operation and Care of
DEHUMIDIFYING PROOFING CABINET
SAVE THESE INSTRUCTIONS
GENERAL
The Dehumidifying Proong cabinets proof racks of dough products under controlled temperatures and
humidity prior to baking. The standard Dehumidifying Proofers are equipped to proof dough only.
All Dehumidifying Proong cabinets have easy-to-clean stainless steel interior and exterior panels.
It is suggested that you thoroughly read this manual and carefully follow the instructions provided.
INSTALLATION
Dehumidifying Proofers must be installed by authorized trained service technicians.
OPERATION
The following pages cover the operation procedures for the Dehumidifying Proong Cabinet.
DEHUMIDIFYING/PROOFING
Controlled temperature and humidity in the proofer promotes yeast fermentation, which generates gas and
causes the dough to rise. Proong takes from 40 to 50 minutes, depending on the product. A temperature
setting of 105°F (40°C) and humidity at 63% are typical but will vary slightly, depending on the product
being proofed. Three pre-programmed proong cycles are supplied in the control memory. The chart below
explains the three Dunkin-approved proong cycles pre-programmed into the control.
Product Temperature % Humidity Time Minutes
1st Cut Product & Munchkin 105°F (40°C) 63% 40 min.
2nd Cut Product 105°F (40°C) 63% 45 min.
3rd Cut Product 105°F (40°C) 63% 50 min.

SELECT PROOFER MODEL VIA BOOTLOADER
The proofer model is set at the factory. However, if the proofer model needs to be changed this procedure
shall be followed.
1. Turn o the Proofer with the ON/OFF button.
2. Hold these three buttons, in this order for 5 seconds.
• HUMIDITY DOWN ARROW
• TEMPERATURE UP ARROW
• ON/OFF Button.
3. Keep holding the three buttons until "conF" is shown in the Temperature display (Fig. 14).
Fig. 14
4. The current proofer conguration value will be displayed in the HUMIDITY display. 1, 2 or 3
5. Pressing the HUMIDITY UP ARROW will cycle through the congurations, 1, 2 or 3
• Cong 1: Proofer (PW)
• Cong 2: Retarder/Proofer (RPW)
• Cong 3: Dehumidifying Proofer (DPC1S)
6. The conguration is saved by pressing the ON/OFF button.
7. The TEMP and HUMIDITY display LEDs will ash on and o for two seconds to indicate that the
new conguration has been saved.
8. The proofer control board will reboot with the new conguration.
NOTE: If the application rmware is corrupt or missing, the unit will enter the bootloader automatically.
This will happen even if you do select a proofer model, it will still return to the bootloader where you are
required to load the rmware. To correct this error, update the proofer rmware.

onto a FAT formatted ash drive.
2. Turn o the Proofer with the ON/OFF button.
3. Insert the ash drive into the proofer’s USB
socket (Fig. 15).
4. Hold these three buttons, in this order for
5 seconds.
• HUMIDITY DOWN ARROW
• TEMPERATURE UP ARROW
• ON/OFF button.
5. Keep holding the three buttons until "conF" is

update.
9. "UPdt" will be displayed in the TEMP display for 1 second.
10. "Strt" will be displayed in the TEMP display for 1 second.
11. The image le will be validated.
• On a successful update "Succ" will be displayed on the TEMP display for 2 seconds. The control
board will reboot. Remove ash drive and turn on the proofer with the ON/OFF button. Verify
the correct proofer operating mode and parameters.
• On an unsuccessful update "Err" will be displayed on the TEMP display, this will be permanently
displayed and the proofer will need the power cycled to clear this error. Depending on the cause
of the failure either the old application will run if still present or the system will enter into the
bootloader so you can attempt to ash again.

CONTROL BOARD POWER UP
Each time power is applied to the control board, the bootloader is launched. The bootloader looks at the
ash conguration to choose which of the three conguration modes to use.
During the boot up process, the conguration mode number 1, 2, or 3 is displayed in the HUMIDITY display
for several seconds.
This function is used to help the technicians verify the proofer control board is congured correctly.
LCD CONTRAST ADJUSTMENT
If the control board includes an LCD, this procedure can be followed to adjust the LCD contrast.
Enter Bootloader:
1. Turn o the Proofer with the ON/OFF button.
2. Hold these three buttons, in this order for 5 seconds.
• HUMIDITY DOWN ARROW
• TEMPERATURE UP ARROW
• ON/OFF button.
3. Keep holding the three buttons until "conF" is shown
in the Temperature display (Fig 14).
4. The current proofer conguration value will be
displayed in the HUMIDITY display. 1, 2 or 3.
5. While in the normal bootloader mode, hold down the
HUMIDITY DOWN button and then press the TEMP
UP button. You will see the LED display change and
the LCD will display the instructions (Fig. 17). The
system is now in LCD contrast setting mode.
6. Using the HUMIDITY UP and DOWN buttons set the
LCD contrast as desired.
7. Once satised with the LCD contrast setting, press
the TEMP UP button to save the setting and exit the
LCD contrast mode. You will return to the bootloader
mode.
8. Once back in the bootloader mode, set the desired
conguration and press ON/OFF button to start the application.
